A person goes on a slimming diet. already existing apps sense the calories in the food they prepare, this trashcan apps tells you how many calories you save when you leave food unfinished on your plate.

I mean well, yet my portion sizes seem a little larger than I intend. What if I had the diet idea "just eat some of it." Then the talking trashcan could say "you saved 200 calories" when I pitch the mac n cheese in the trash, making me feel i had accomplished something?

Now the rational approach
would be to make less food in the first place. The thing is how many people are rational? Planning meals requires sustained purpose, while just tossing it might be an impulse, so easier to generate. Globally the largest predicted health problems are associated with overweight, so a system that verbally congratulates when tossing food could actually be beneficial.

I know it seems wasteful, yet if they made one and tested it, it might cause people to be slimmer.

//the rational approach would be to make less food in the first place. //

No. The rational approach would be to make more food, so that a larger portion could be consigned to the intelligent trashcan. Supermarkets could, in fact, sell "trashcan ready" meals that were calorie-packed and unpalateable. Oh, wait...

Then eat whenever you're hungry till you're full. If you get
off the sugar/bad carb addiction your hunger hormone,
ghrelin, won't be all out of wack sending you "eat" messages
when you shouldn't be eating.

If you want to start out slow, just cut sugary drinks out of
your diet, that includes fruit juice which is no different
than Coke or Pepsi to your body.

If you need more information you didn't read this correctly.
Go back and read it again as many times as you need to.

Well, I will make half this annotation on topic RE:
trashcans, and half off topic on diet advice

humblebragging/hubris: actually Im BMI 23.2

Diet advice: go vegetarian

Drug advice: Take metformin, it makes lab mammals live
longer, and makes people weigh about 12 lbs less.

Trashcan content: If the app that measures how much
food you have on your plate collaborates with the smart
trashcan and you are 300 calories under maintenance
calories then you could get free videogame levels.

Throwing out (still-good) food is a bad idea. Put it in the fridge!
(Aside: some weeks it's not worth the effort for me to put my bin out for collection; there's so little in it, because I try to be efficient in my rubbishing.)

Disproven bad science. We're not yet adapted to
the agricultural revolution that was only a couple
of seconds ago on an evolutionary time frame.
We're omnivores adapted to a meat and vegetable
diet in keeping with what we foraged and hunted
as, remember what we were called? Hunter
gatherers.

We took over the planet because of our ability to
eat and adapt to anything. We can survive on
candy bars and maybe someday we'll adapt to
thrive on those, but in the meantime, our bodies
are wanting the same thing they've always wanted:
Meat, fat, and to get our vitamin C so we don't get
scurvy, green vegetables, which have plenty of
vitamin C.

Ask the primative eskimo societies with zero heart
disease or metabolic syndrome about vegetarian
diets. (Next time you find yourself chatting with a
primative eskimo society.)

And if anybody ever suggests eating "heart healthy
grains" (a slogan dreamed up by the grain industry,
the same people that invented the debunked food
pyramid)
don't listen to anything else they say about
anything ever.

That being said, grains and the agricultural
revolution allowed us to have cities and
indeed civilizations. But your body isn't impressed.

As for exercise, nothing beats heavy weight lifting.
I run as well but it's pretty un-natural and can be
bad for you. We're designed to walk long distances
and sprint for short periods of time, (forage, stalk
prey,
run it down) but there's no reason in nature for us
to run at medium speed for two or three hours.
Though I do it anyway sometimes because...
well...
other people do it.

As for my body type, I had a fat person call me a
"gym rat" once, judging me only by my physique to
which I responded "Better than
being a couch slug."

// This is insane. The thing we must avoid is throwing away anything that has potential. We must find ways to make use of everything as far as possible. Waste is the enemy. //

So very true. Every year, literally hundreds of perfectly useable explosive devices are destroyed out of hand by gumment agents, on the grounds of "safety" (allegedly). HAH ! They just want to spoil everyone's fun. Just because a device is over seventy years old, corroded, potentially unstable, and in an awkward spot is no reason to just waste it.

There has to be a better way, by which the full entertainment value of such treasure trove can be extracted. Sadly, so far, all our efforts in that direction have met with nothing but obstruction by the authorities. Mean, we call it.

That is true but I bet you would find that their diet would kill most people not used to it... oh and they call themselves Inuit. Eskimo means "one who laces snowshoes" and they find it insulting I hear.If you were to take inuit babies and force them to eat a Polynesian or Indian diet they would probably not live a long and healthy life.

There was a study done not too long ago involving full-blood American natives with diabetes. They were kept on a strict diet of what their ancestors would have eaten before Wallmart, nuts, wild meat and fish, corn, pemmican, bannock etc. and to a person their diabetes was not only controlled but disappeared. Can't find the actual study anymore of course, but it was a good one.

Well, were did we get the name from? If eskimo is Inuit for
"Dirty snowshoe lacing bastard" or whatever, we didn't make
it up, they did. They shouldn't have introduced us to the
term. There I go, blaming the Eskimos for everything again.

But yes, modern Inuit have horrible health just like
everybody who's adopted the grain / sugar based diet.

//That only applies to Type 1 diabetics. Sugar
spikes are only relevant to not overweight people.
GI is just such rubbish for Type 2's and is actually
very dangerous as it promotes unnecessary
snacking.//

So eating vegetables is dangerous if you've got type
2 diabetes and high blood sugar isn't an issue as long as
you're obese?

It's this kind of revolutionary going against the
prevailing wisdom that sells books! You've got a big
future in the publishing game!
